Long-term phosphorus trial - 2008 report locations
Aims

To ascertain the long-term benefits in crop growth and profitability as a result of regular phosphorus (P) applications.

Key messages
  • There was no significant yield difference between any of the P rates in 2008
  • The most profitable application rate of P on average between 2003 and 2008 has been zero on a site with a strong fertiliser history and initial soil P Colwell of 41ppm
  • Maintenance rates of 5kg/ha, produced the second highest net income with the least amount of risk
  • Avoid making fertiliser decisions on ‘gut feel’. Make use of tools such as soil tests and nutrient balances to determine P rates in 2009.
